Please consider it during use. 2) The maximum output current of the analog terminal is 1 mA, and the drive may be damaged if 3.7 Brake this is exceeded. Please consider it fully when selecting the load.
When the motor is used to drive the vertical axis or under similar conditions (e.g. external force), a motor with a brake is required in order to prevent the movement of moving parts due to gravity or external force in case of power failure. External 24V power supply is needed for brake. The wiring methods of brake signal and power supply are as follows:
37 Pin Circuit diagram Signal Pin # Function distribution AO1 1 Analog output 1, output voltage -10V ~ 10V, maximum output current 1mA The correspondin g output information can be set by the P6 group codes 4 3 CN1 2 1 (front view when servo drive is vertical) Servo drive 1AO1 A 2 AO2 A 3 GND AO2 2 Analog output 2, output voltage -10V ~ 10V, maximum output current 1mA GND 3 Analog output signal common ground Reserved 4 Cannot connect to any signal cable Attention☞ 1. The brake is only used for keeping the motor in a stopped state and must not be used to stop the operation of the motor. 2. The brake may give off clicking sound when the motor runs, but it does not affect its function.
